Matricaria discoidea, commonly known as pineappleweed, wild chamomile, and disc mayweed is an annual plant native to North America and Northeast Asia but which has become a cosmopolitan weed. It is in the family Asteraceae. The flowers exude a chamomile/pineapple aroma when crushed. They are edible and have been used in salads (although they may become bitter by the time the plant blooms) and to make herbal tea. Pineapple weed has been used for medicinal purposes, including for relief of gastrointestinal upset, infected sores, fevers, and postpartum anemia.

Description

The pinnately dissected leaves are sweet-scented when crushed (Fir Island, Washington).

The flower head is cone-shaped, composed of dense-packed yellowish-green corollas, and lacking ray-florets. The leaves are pinnately dissected and sweet-scented when crushed. The plant grows 2 to 16 inches (5.1 to 41 cm) high. Flowerheads are produced from May to September.

Distribution

The plant grows well in disturbed areas, especially those with poor, compacted soil. It can be seen blooming on footpaths, roadsides, and similar places in spring and early summer. In North America, it can be found from central Alaska down to California and all the way to Nova Scotia.

Uses

Pineapple weed flowers used to be gathered for food by children, although most find it too bitter to consume raw. The plant, when bruised and rubbed on skin, provides an effective, yet temporary insect repellent.

The young flower heads can be used to make tea by steeping a handful of the flowers in hot water for ten minutes and then straining.
